    摘要： A main valve for a thrust piston motor wherein two angled bores of the control piston of the main control valve terminatein the zone of a restriction of the piston in first and second radial outlet ports, the axial distance between which is substantially equal to the length of the restriction, and in that the slide carries in a zone of the restriction a displaceable control sleeve mounted thereon acting as a movable supplementary valve element, and so dimensioned that in one end position it closes the outlet of the first channel and opens the outlet of the second channel, and in the other end position it opens the outlet of the second channel and closes that of the first channel.

    摘要： A control device for a thrust piston motor consisting of two normally closed auxiliary control valves and one main control valve, controlled by the auxiliary control valves, and containing a control piston adapted to be displaced by the action of the fluid medium and a control slide coupled with the control piston for controlling the direction of movement of the motor piston, and wherein the control pressure chambers are each connected by a bore provided in the control piston and a supplementary valve means connected to the control piston, with a pressure medium source and through one of the auxiliary control valves each with a low pressure zone the improvement comprising that for obtaining an externally controlled sequence of individual strokes, one control valve (first control valve) is operable externally and the other control valve (second control valve) by the motor piston during the passage through a dead centre position, wherein there is mounted, on the side of the motor piston remote from the second control valve in the motor cylinder, an abutment stop in such a manner that its distance from the second control valve is variable.
